DNS settings in Windows

If you occasionally encounter a situation where a website does not work and you receive the error "DNS_PROBE_FINISHED_NXDOMAIN," the only permanent solution is to reconfigure the DNS in Windows (and possibly on your mobile phone (we will show you how to do this as well)) to Cloudflare or Google. Both are stable.

First, I will write down the IP addresses for Cloudflare and Google that we will need:

Cloudflare (IPv4):
    - Preferred DNS: 1.1.1.1
    - Alternative DNS: 1.0.0.1
Cloudflare (IPv6):
    - Preferred DNS: 2606:4700:4700::1111
    - Alternative DNS: 2606:4700:4700::1001
Cloudflare (Android): 1dot1dot1dot1.cloudflare-dns.com

Google (IPv4):
    - Preferred DNS: 8.8.8.8
    - Alternative DNS: 8.8.4.4
Google (IPv6):
    - Preferred DNS: 2001:4860:4860::8888
    - Alternative DNS: 2001:4860:4860::8844
Google (Android): dns.google

Windows:

• Now open Windows Settings, go to the "Network & Internet" section, and click (in my case) on the second item (Ethernet).
• Here we find "DNS server assignment" -> click on "Edit" on the right.
• Now check "IPv4" and "IPv6." Theoretically, IPv4 alone would suffice, but omitting IPv6 may occasionally result in a so-called "DNS leak."
• Enter the value from the code above into IPv4 Preferred DNS, i.e. (in the case of Cloudflare) "1.1.1.1". Enter 1.0.0.1 into Alternative DNS (again, in the case of Cloudflare).
• Then, enter the values from the code above into IPv6 again, but this time for IPv6.

Android:

• This will vary slightly for each device. However, if you have Android 9 or higher, you have the option of "Private DNS" in the settings. Here, you can enter the IP (in the case of a mobile phone, it is more commonly referred to as a text string) from the code above -> "Cloudflare (Android)" or (for Google) "Google (Android)".

Well, we're done. Now all websites should work as they should and should even load a little faster, because some operators don't have as stable DNS as large (companies?) such as Google and Cloudflare.
